The Aprilia Sportcity high beam and low beam headlight bulbs both utilize an H7 size. The replacement chart covers vehicle production spanning 2007 to 2011 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base, which is a two-pin locking connector designed to secure the bulb in a fixed rotational position within the housing.
The H7 bulb carries ECE certification, meaning it meets the regulatory lighting standards used across Europe and numerous other markets worldwide, and it also holds approval in the United States and Japan.
The Aprilia Sportcity uses the H7 bulb for both the high beam and low beam headlight positions across the 2007-2011 model years.
Because both beam positions share the same H7 specification, the two sockets are physically and electrically identical, though the housings they occupy are separate and serve distinct optical functions.
The single-filament construction of the H7 means each bulb controls only one beam function, which is why two separate H7 units are required to cover both high and low beam operation.
The PX26d base is not interchangeable with other common halogen bases such as the H4's P43t or the H1's P14.5s, so substitution with those bulb types is not possible without modifying the socket.
